1GHz Renesas RA8T2 Cortex-M85 MCUs feature MRAM and EtherCAT for industrial motor control
Renesas has recently introduced the new RA8T2, an AI-powered motor control Cortex-M85 MCU that can be considered a direct upgrade to the RA8T1, which launched last year. The RA8T2 offers higher performance along with networking options for industrial, robotics, and other motor control systems. The RA8T2 features a 1GHz Arm Cortex-M85 core, an optional 250MHz Cortex-M33 core, up to 1MB MRAM and 2MB SRAM, a 300MHz PWM timer, dual 16-bit ADCs with simultaneous sampling, high-speed comparators, fast PWM shutdown, and more. Connectivity options include dual Gigabit Ethernet, EtherCAT slave, USB, CAN FD, I3C, and SPI, while security features include TrustZone...
Easily add 80+ Mbps Ethernet to microcontrollers with WIZ630io QSPI RJ45 module
WIZnet WIZ630io is a small module featuring an RJ45 jack and a W6300 controller supporting up to 80+ Mbps Ethernet over QSPI @ 150 MHz. As a reminder, the W6300 features 64KB of SRAM for 8 sockets, each with a 4KB TX/RX buffer by default. It is notably found in the WIZnet W6300-EVB-Pico2 development board powered by a Raspberry Pi RP2350 MCU. The WIZ630io allows you to easily add Ethernet to any RP2350 board or other microcontroller with a SPI or QSPI interface. WIZnet WIZ630io specifications: W6300 QSPI Ethernet controller Host Interface – High-speed QSPI (MODE 0/3), system bus with...
R1 Neo Meshtastic Device Introduced with GPS and nRF52840 Processor
The R1 Neo from Muzi Works is a compact, water-resistant Meshtastic device designed for long-range communication and GPS-based location tracking. Developed and assembled in Atlanta, it is the company’s first model built on a custom PCB featuring a dedicated I/O controller and integrated power management. The unit is powered by a Nordic nRF52840 microcontroller paired […]
kv4p HT – Turn an Android smartphone into a ham radio transceiver
kv4p HT is an open-source hardware VHF or UHF radio designed to plug into the USB-C port of an Android smartphone and turn it into a handheld ham radio transceiver. It’s based on an ESP32 wireless module and an SA818 radio module. This accessory makes your phone capable of off-grid voice and text communication with a Technician-class amateur radio license. It’s small enough to fit into a pocket, partially because it does not need a battery, relying on the built-in battery of your phone. kv4p HT V2.0 specifications: Wireless module – ESP32-WROOM-32E-N4 SoC – ESP32 dual-core Tensilica LX6 microcontroller @...
Terasic Announces Starter Kit Featuring RISC-V Nios V Processor and Software Bundle
Terasic has introduced the Atum Nios V Starter Kit, a feature-rich evaluation platform designed to accelerate development with Altera’s Nios V processor. The kit is aimed at embedded engineers, system developers, and educators looking for a practical way to explore RISC-V–based designs on the Agilex 3 FPGA platform. According to Terasic’s announcement, the kit is […]

Amazon has recently introduced the Fire TV Stick 4K Select media streamer with a MediaTek MT8698 quad-core Cortex-A55 processor, 1GB RAM, 8GB eMMC flash, HDMI 2.1 video output, and WiFi 5 and Bluetooth 5.0 connectivity. However, the most interesting part of the announcement is the software, as Amazon has dropped the Android-based Fire OS used in its previous devices and instead relies on the new Linux-based Vega OS for the Fire TV Stick 4K Select. Amazon Fire TV Stick 4K Select (AFTCA002) specifications: SoC – MediaTek MT8698 MCM CPU – Quad-core Arm Cortex-A55 clocked up to 1.7 GHz GPU –...
Free Stuff - July 2025
The belated July 2025 recipient for the Great Scott Gadgets Free Stuff Program is Murat Sever, a professor from Turkey who teaches at TOBB ETU University and recently ran a workshop titled “Simple Replay Attack Demo with GNU Radio.” In this workshop, Murat utilized several open-source software and hardware tools to demonstrate how to receive and transmit RF signals. Workshop participants then used SDR and GNU Radio to perform replay attacks with the captured radio signals. We sent a handful of HackRF Ones to Murat for participants to learn and experiment with in this workshop. He has also informed us...

Радиолампы (они же — электронные лампы), несмотря на вопиющее моральное устаревание, до сих пор интересуют и интригуют, взять тот же пресловутый «ламповый звук». Интересны и их история, технология, конструирование, вплоть до самостоятельного любительского изготовления лабораторных образцов. Простой вопрос в этом смысле неожиданно увлёк в дебри электровакуумной технологии. Итак — зачем же некоторым приёмно-усилительным лампам (ПУЛ) сетчатые аноды — натурально, решето, тогда как этот электрод должен принимать поток электронов с катода и получше рассевать образовавшееся тепло?
